If device is busy and you can’t umount it, try it with -l option (lazy unmount). Or you can force it.
# standard umount /mnt/data # lazy umount umount -l /mnt/data # force umount -f /mnt/data |
# standard umount /mnt/data # lazy umount umount -l /mnt/data # force umount -f /mnt/data
Lazy unmount is safer since it will detach immediately and clean up all references to the file system. Force is a bit more drastic.
Here’s the command to mount and unmount AWS EFS. Assuming the EFS IP address is 10.0.0.23.
Mount:
mount -t nfs -o nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport 10.0.0.23:/ /efs |
mount -t nfs -o nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport 10.0.0.23:/ /efs
Umount:
# lazy unmount umount -l /efs # force unmount umount -f /efs |
# lazy unmount umount -l /efs # force unmount umount -f /efs
You may have to force it if it’s busy.
